What's new in this version:

- Fix persistence marking of shared buffers during WAL replay
- Fix possible incorrect sorting of output from queries involving WHERE indexed_column IN (list_of_values)
- Fix planner failure for queries involving GROUP BY expressions along with window functions and aggregates
- Fix planner's assignment of executor parameters
- This error could result in wrong answers from queries that scan the same WITH subquery multiple times.
- Improve planner's handling of join conditions in index scans
- Improve selectivity estimation for text search queries involving prefixes, i.e. word:* patterns
- Fix delayed recognition of permissions changes
- A command that needed no locks other than ones its transaction already had might fail to notice a concurrent GRANT or REVOKE that committed since the start of its transaction.
- Fix ANALYZE to not fail when a column is a domain over an array type
- Prevent PL/Perl from crashing if a recursive PL/Perl function is redefined while being executed
- Work around possible misoptimization in PL/Perl
- Some Linux distributions contain an incorrect version of pthread.h that results in incorrect compiled code in PL/Perl, leading to crashes if a PL/Perl function calls another one that throws an error.
- Remove unnecessary dependency on pg_config from pg_upgrade
- Update time zone data files to tzdata release 2012f for DST law changes in Fiji
